Book excerpt: Understanding the causes and consequences of biological diversity remains the unifying goal of ecology and evolutionary. One promising avenue to understand the causes and consequences of genetic diversity within populations is to consider correlations between that genetic diversity and species diversity of the community in which it resides. Both genetic and species diversity can respond to locality characteristics, or each level can influence and be influenced by the other. First, I investigate how area connectivity and gene flow affects the population genetic diversity patterns in the California vole (Microtus californicus). I show that migration across the landscape produces an identical genetic patterns at the local and regional spatial scales in this small mammal (Chapter 1). Next, I explored two ways in which genetic and species diversity influence each other. In one approach, I examine the effects of a species-rich competitor community on the genotypic diversity of a focal community when genetic diversity allows for differential strength of competition with different species. Using computer simulations, I show that species diversity of competitors can act as an important promoter of genotypic diversity within species (Chapter 2). Next, moving to a riparian community in northern Utah, I demonstrate that the genetic diversity of a foundation tree correlates positively with the species diversity of understory plants, including forbs, grasses, and vines (Chapter 3). Finally, I show that both genetic diversity and species richness across the globe show a similar pattern: genetic markers in over 70 vertebrate species show a significant trend of higher diversity at low latitudes than at higher latitudes (Chapter 4). By taking a broad approach to understanding the causes and consequences of intraspecific genetic diversity, with a particular focus on links to species diversity patterns, my dissertation finds general principles that operate across systems. The two levels of diversity can influence each other by creating spatially-varied selection regimes, but gene flow and mutation are two processes operating on the genetic level whose power to scale up to influence species-level patterns is highly contextual.

Download or read book The Biology of Biodiversity written by M. Kato and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 451 pages. Available in PDF, EPUB and Kindle. Book excerpt: Biological diversity, or biodiversity, refers to the universal attribute of all living organisms that each individual being is unique - that is, no two organisms are identical. The biology of biodiversity must include all the aspects of evolutionary and ecological sciences analyzing the origin, changes, and maintenance of the di versity of living organisms. Today biodiversity, which benefits human life in vari ous ways, is threatened by the expansion of human activities. Biological research in biodiversity contributes not only to understanding biodiversity itself but also to its conservation and utilization. The Biology of Biodiversity was the specialty area of the 1998 International Prize for Biology. The International Prize for Biology was established in 1985 in commemoration of the sixty-year reign of the Emperor Showa and his longtime devotion to biological research. The 1998 Prize was awarded to Professor Otto Thomas Solbrig, Harvard University, one of the authors of this book. In conjunction with the awarding of the International Prize for Biology, the 14th International Symposium with the theme of The Biology of Biodiversity was held in Hayama on the 9th and 10th of December 1998, with financial support by an international symposium grant from the Ministry of Education, Science, Sports and Culture of Japan. The invited speakers were chosen so as to cover four basic aspects of biodiversity: species diversity and phylogeny, ecological biodiversity, development and evolution, and genetic diversity of living organisms including human beings.
Download or read book Speciation and Patterns of Diversity written by Roger Butlin and published by Cambridge University Press. This book was released on 2009-01-22 with total page 565 pages. Available in PDF, EPUB and Kindle. Book excerpt: Bringing together the viewpoints of leading ecologists concerned with the processes that generate patterns of diversity, and evolutionary biologists who focus on mechanisms of speciation, this book opens up discussion in order to broaden understanding of how speciation affects patterns of biological diversity, especially the uneven distribution of diversity across time, space and taxa studied by macroecologists. The contributors discuss questions such as: Are species equivalent units, providing meaningful measures of diversity? To what extent do mechanisms of speciation affect the functional nature and distribution of species diversity? How can speciation rates be measured using molecular phylogenies or data from the fossil record? What are the factors that explain variation in rates? Written for graduate students and academic researchers, the book promotes a more complete understanding of the interaction between mechanisms and rates of speciation and these patterns in biological diversity.

Download or read book From Assessing to Conserving Biodiversity written by Elena Casetta and published by Springer. This book was released on 2019-06-17 with total page 455 pages. Available in PDF, EPUB and Kindle. Book excerpt: This open access book features essays written by philosophers, biologists, ecologists and conservation scientists facing the current biodiversity crisis. Despite increasing communication, accelerating policy and management responses, and notwithstanding improving ecosystem assessment and endangered species knowledge, conserving biodiversity continues to be more a concern than an accomplished task. Why is it so?The overexploitation of natural resources by our species is a frequently recognised factor, while the short-term economic interests of governments and stakeholders typically clash with the burdens that implementing conservation actions imply. But this is not the whole story. This book develops a different perspective on the problem by exploring the conceptual challenges and practical defiance posed by conserving biodiversity, namely: on the one hand, the difficulties in defining what biodiversity is and characterizing that “thing” to which the word ‘biodiversity’ refers to; on the other hand, the reasons why assessing biodiversity and putting in place effective conservation actions is arduous.

Download or read book Species Diversity and Community Structure written by Teiji Sota and published by Springer Science & Business Media. This book was released on 2013-08-30 with total page 70 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book introduces recent progress in the study of species diversity and community structures in terrestrial organisms conducted by three groups at Kyoto University. First, it explains species diversity and the functioning of fungi in Asian regions as outlined by metagenomic approaches using next-generation sequencing technology. The advances in high-throughput sequencing technologies accelerate the speed of species inventorying, especially for microorganisms. Second, the study of complex interactions between herbivorous insects and plants in the community and ecosystem contexts is presented. Recent studies in community and ecosystem genetics shed light on these complex interactions with novel approaches incorporating genetic perspectives including genetic variation and phenotypic plasticity in plant defenses against herbivores. Finally, recent studies on speciation processes in insects are described, processes that are related to the evolution of particular life history strategies. Included is an examination of two hypotheses that may be important in understanding diversification of insect species in heterogeneous environments in space and time. This book is a valuable resource especially for ecologists who are interested in species diversity and community structure.
Download or read book Biodiversity Conservation and Phylogenetic Systematics written by Roseli Pellens and published by Springer. This book was released on 2016-02-24 with total page 396 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is about phylogenetic diversity as an approach to reduce biodiversity losses in this period of mass extinction. Chapters in the first section deal with questions such as the way we value phylogenetic diversity among other criteria for biodiversity conservation; the choice of measures; the loss of phylogenetic diversity with extinction; the importance of organisms that are deeply branched in the tree of life, and the role of relict species. The second section is composed by contributions exploring methodological aspects, such as how to deal with abundance, sampling effort, or conflicting trees in analysis of phylogenetic diversity. The last section is devoted to applications, showing how phylogenetic diversity can be integrated in systematic conservation planning, in EDGE and HEDGE evaluations. This wide coverage makes the book a reference for academics, policy makers and stakeholders dealing with biodiversity conservation.
Download or read book The Nature of Diversity written by Daniel R. Brooks and published by University of Chicago Press. This book was released on 2012-04-26 with total page 684 pages. Available in PDF, EPUB and Kindle. Book excerpt: All living things on earth—from individual species to entire ecosystems—have evolved through time, and evolution is the acknowledged framework of modern biology. Yet many areas of biology have moved from a focus on evolution to much narrower perspectives. Daniel R. Brooks and Deborah A. McLennan argue that it is impossible to comprehend the nature of life on earth unless evolution—the history of organisms—is restored to a central position in research. They demonstrate how the phylogenetic approach can be integrated with ecological and behavioral studies to produce a richer and more complete picture of evolution. Clearly setting out the conceptual, methodological, and empirical foundations of their research program, Brooks and McLennan show how scientists can use it to unravel the evolutionary history of virtually any characteristic of any living thing, from behaviors to ecosystems. They illustrate and test their approach with examples drawn from a wide variety of species and habitats. The Nature of Diversity provides a powerful new tool for understanding, documenting, and preserving the world's biodiversity. It is an essential book for biologists working in evolution, ecology, behavior, conservation, and systematics. The argument in The Nature of Diversity greatly expands upon and refines the arguments made in the authors' previous book Phylogeny, Ecology, and Behavior.
